Dolmarehn - Book Two of the Otherworld Trilogy by Jenna Elizabeth Johnson

A year ago, Meghan Elam learned that she was Faelorehn, a being of the Otherworld. Immortal. Only when her visions grew worse and when a mysterious boy appeared to help guide her, did she finally come to realize exactly who and what she was. But the questions didn’t end there, and Meghan is only just beginning to find the answers. Now she must juggle her life in the mortal world with the one she has started to build in the Otherworld. However, keeping her identity secret from her friends and family while trying to avoid a wrathful Celtic goddess is no easy task. With the help of her newfound friend and savior, Cade MacRoich, Meghan will gradually learn that not only does she come from a place full of magic and wonder but that she, too, is far more powerful than she ever thought possible.
